It's called 'tool usage' and it's the reason humans have triumphed thus far. We create better tools to handle tasks so we don't need to expend energy on them; thus not learning/utilizing outdated methods or remembering information which can be easily looked up is an advantage.

Paraphrasing an(assumed) Einstein quote, 'Don't bother to remember anything you could look up.'. These days the greatest advantage a person can possess in most any situation is the ability to competently utilize a search engine. I think we should be stressing the younger generations to further adapt to technology rather than learning old methodology. You're much better off learning how to use a calculator than learning long division.
